Researchers Investigate New Targeted Therapy for Metastatic Prostate Cancer

Excerpt:

“Men with localized prostate cancer face good odds: Their relative five-year survival rate is nearly 100 percent. However, men with metastatic disease — prostate cancer that has spread to another organ like the lungs — have a relative five-year survival rate of only 29 percent.

“Currently, the mainstay treatment for metastatic prostate cancer is hormone therapy, which uses drugs to lower the levels of male sex hormones like testosterone in the body to slow the growth of prostate cancer. Two of the latest hormonal agents, abiraterone acetate and enzalutamide, have shown some improvements in overall survival. Unfortunately, hormone therapy isn’t a cure and most patients become resistant to the drugs.”

Dual HER2-Blockade Plus AI Shows Promise in HER2+/ER+ Breast Cancer

Excerpt:

“Data from the phase II PERTAIN trial presented late last year at the 2016 San Antonio Breast Cancer Symposium (SABCS) showed that adding an aromatase inhibitor (AI) to pertuzumab (Perjeta) and trastuzumab (Herceptin) extended progression-free survival (PFS) by over 3 months versus trastuzumab plus an AI in patients with HER2-positive, HR-positive locally advanced or metastatic breast cancer.

“The median PFS was 18.89 months with the pertuzumab triplet compared with 15.80 months for trastuzumab and an AI alone (HR, 0.65; 95% CI, 0.48-0.89; P = .007). The objective response rates were 63.3% versus 55.7%, respectively.”

Fulvestrant Prolongs PFS for Women with Hormone Receptor– Positive Advanced Breast Cancer

Excerpt:

“Fulvestrant prolonged PFS compared with anastrozole among women with hormone receptor– positive locally advanced or metastatic breast cancer who have not received previous endocrine therapy, according to a phase 3, randomized, double blind trial published in The Lancet.

” ‘The primary endpoint of this phase 3 study was met, with patients receiving fulvestrant having a significantly longer PFS than patients receiving anastrozole,’ John F.R. Robertson, MD, a professor at University of Nottingham Medical School and Royal Derby Hospital Centre in Derby, United Kingdom, and colleagues wrote. ‘This represents a meaningful and relevant finding for which clinical data are limited.’ ”

Breast Cancer Patients’ Distress at Withdrawal of Kadcyla

Excerpt:

“Terminal breast cancer patients have spoken of their distress after learning that a life-extending drug they had been told would be available to them looks set to be withdrawn.

“Advisory body NICE is reviewing drugs made available through the old cancer drugs fund, and has rejected Kadcyla for use on the NHS in England.

“It believes the price per patient set by manufacturer Roche is too expensive. Roche says discussions are continuing.”

New Study Aims to Extend TTFields Beyond Grade IV Brain Cancer Domain

Excerpt:

“The use of tumor treating fields (TTFields) as a treatment for patients with brain tumors has, thus far, largely been focused on in glioblastoma, but an upcoming trial aims to expand the use of the device to the grade III patient population, says Daniel O’Connell, MD.

“Currently, the device is only FDA approved for use in grade IV brain tumors, but O’Connell, a neuro-oncologist at UCLA’s David Geffen School of Medicine, anticipates the FDA will grant its approval for use in grade III tumors within the next 2 to 3 months.”

NCCN Publishes Patient Education Resources for Gliomas—Its First in a Series on Brain Cancer

Excerpt:

“January 9, 2017) The National Comprehensive Cancer Network® (NCCN®) has published the NCCN Guidelines for Patients® and NCCN Quick Guide™ sheets for Brain Cancer – Gliomas—the first in a series of patient education resources focused on Brain Cancer. Published by NCCN through support of the NCCN Foundation®, and, in part through funding from NCCN Foundation’s Team Pound the Pavement for Patients, these resources inform patients about their disease and the treatment options available to them.”

Attacking Glioblastoma by Combining Immune Checkpoint Inhibitors with Gene Therapy Looks Promising

Excerpt:

“Attacking an aggressive brain tumor with immunostimulatory gene therapy while enhancing the immune system’s ability to fight it with immune checkpoint inhibitors might be a promising approach to treat patients with glioblastoma multiforme, a brain tumor currently associated with a very poor prognosis.

“The findings from the study, “Immunosuppressive Myeloid Cells’ Blockade in the Glioma Microenvironment Enhances the Efficacy of Immune-Stimulatory Gene Therapy,” published in Molecular Therapy, revealed that combining both these approaches in glioblastoma mice models significantly extended their survival, compared to either treatment alone.”

Pegram Sheds Light on Margetuximab in HER2+ Breast Cancer

Excerpt:

“The Fc-modified monoclonal antibody margetuximab in combination with chemotherapy may offer a new treatment option for patients with HER2-positive metastatic breast cancer.

“In the ongoing phase III SOPHIA trial (NCT02492711), researchers are comparing margetuximab plus chemotherapy with trastuzumab (Herceptin) plus chemotherapy. In a previous phase I study, margetuximab demonstrated single-agent activity in HER2-positive tumors, leading researchers to explore the regimen in the phase III trial.”

Midgut Neuroendocrine Tumor Prognosis

Excerpt:

“Patients with small intestine neuroendocrine tumors often have mesenteric tumor deposits (MTDs) in the abdomen – discrete tumor nodules that are not connected to the primary tumor. The clinical significance of these tumor deposits has not been thoroughly investigated, and they are not included in the American Joint Committee on Cancer (AJCC) staging system for midgut neuroendocrine tumors.

Chanjuan Shi, M.D., Ph.D., and colleagues examined the prognostic significance of MTDs associated with midgut neuroendocrine tumors in 132 patients. Using pathologic slides from resected tumors and electronic medical records, the researchers reviewed AJCC tumor stage, lymph node and liver metastasis, presence of MTDs and survival data.”
